LOCK.

Specification of Letters Patent.

raitented sept. 1c, 191e.

Application ined 'May 3, 191e. serial No. eases.

To all whom it may concern:

Be it known that 1, ALBERT A. PAGE, a citizen of the United y States,residing in East Haven, `in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in Locks,of which the following is a full, clear, and exact description.

rlhis invention relates to locks, and more particularly to locks of themortise type intended to be applied to metal doors. The 1nveution alsorefers especially to means for securing a mortise look within a hollowmetal door stile.

1n applying mortise locks to hollow metal doors, considerabledifiiculty` has been encountered heretofore by reason of the fact thatthe door stile usually has to have certain metal reinforcements to whichthe face' plate or front of the lock is screwed or other wiso secured.

Une of the objects of the present invention is to do away with thedirect connection of the front or face plate of the lock to the doorstile and thereby obviate the necessity of inserting' one or more metalplates within the stile.

The invention has also in View the general improvement andsimplification of the construction, whereby the application of the lockto the door is considerably facilitated.

To these and other ends, the invention consists in the novel featuresand combinations of parts to be hereinafter described and claimed.

Fig. S is a detail view of the outside lever handle escutcheon. b

In the drawing, I have shown my 1mprovements applied to a metal doorhaving a hollow stile 10 which, in accordance with the usual practice,isformed as a metal tube of generally rectangular erossesection. At theedge of the door, the stile is provided with an elongated slot 11 toreceive the face plate or front 1Q of a mortise lock 13 housed withinthe stile. The slot 11 extends coinpletely through the wall of theinetal tube and corresponds closely in contour with the face plate 12which fits snugly in said slot with its outer face substantially Hushwith the outer face of the metal tube. The particular thickness of theface plate 12 relativelyto the lthickness of the tube Wall is notmaterial; in the example illustrated, the wall of the tube is somewhatthinner than the face plate, as shown, for example, in Fig. 5. `The faceplate is not directly connected with the tube in any way and need notbe, because the mortise lock 13 is securely fixed in the tube with theface plate in the proper position in its slot in the following,1 manner:At the upper part of the case of the mortiselock 13 is an upwardlyprojecting lug` 14, which is preferably cast on the main body portion 13of the lock case and independent of the cap plate 13b, as shown in Fig.7. Preferably this lug 14 is of thesame thickness as the lock case, oneface of said lug` being; Hush with the cap plate, and the oppositesurface o-f said lug being flush with the back of the lock. A bore orperforation 15 extends through the lug 14 and is adapted to receive anattaching screw 1G passing transversely through the metal tube. At apoint opposite the opening,- 15 of lug 14, the tube 10 is provided atthe outside of the door with an opening` 17 (Fig. 4), in which a button1S is fitted, said button having a flange 18a overlying' the rim of theopening 17; The button has an inwardly projecting socket 19 providedwith interior `screw threads. At the inner side of the door, a button20, somewhat similar to the button 18, is fitted in an opening 21opposite the lug perforation 15, and this button 20 is provided with aninwardly extending Socket and with a bore extending entirely through thebutton and adapted to accommodate the fastening' screw 16 previouslymentioned. Suitable means, such as a pin 22, are provided for preventingthe rotationof the button 18 in the tube wall. This button pre sents asocket or sleeve 19, which is internally threaded, and which is adaptedto abut oneside face of the lug 14, whereas the button 20 has a socketor sleeve portion which is smooth inside, the sleeve being` adapted toabut the lug 14 at the corresponding side.

adapted to engage the threads of the sleeve 19,l and when the screw isscrewed into said sleeve, the mortise lock will be tightly clamped inposition between the sleeves and between the opposite walls of the metalItube. By having the sleeves of the two buttons 18, 2() of the samedepth, and clamping said sleeves against opposite surfaces of the lug14, and clamping the fianges of said buttons against opposite surfacesof the tube, as described, the mortise lock can be securely clamped in aposition centrally of the tube, as will beainderstood.

Means are provided for securing the lock in the tube at the bottom ofthe lock as well as lat the top, and the bottom securing means issomewhat similar to the top secur ing means, although in this case thespacing sleeves are formed on Vthe inside and outside escutcheons 23, 24respectively. In the example. selected for illustration, the mortiselock is provided with a latch bolt 25 adapted to be retracted by insideand outside lever handles 26, 27, and the escutcheons 23, 24 serve asmountings for the respective lever handles. The outside escutcheon 24 isprovided at the upper end with a perforation through which a screw 28 is.screwed into the outer wall of the metal tube 10, as shown in Figs. 1and 5. Similarly, the inside escutcheon 23 is provided at the upper endwith an opening through which a screw 29 is screwed into the inner wallof the tube, as shown in Figs. 3 and 5. At the lower end of theescutcheon ,24, the same is provided with an inwardly extending sleeve30, which engages an opening in the wall of the tube and projectsinwardly into engagement with the face of the lug 14a at the bottom ofthe mortise lock, said sleeve being internally threaded andcorresponding' substantiallyV with the sleeve 19 of the button 18,previously described. At the lowerend of the inside escutcheon 23, thesame is provided with a perforated sleeve 31 generally similar to thebutton or sleeve member 20, and a screw 16b similar to the screw 16BL ispassed through the sleeve 31 and lug 142L into the threaded sleeve 30for screwing the parts together substantially in the manner previouslydescribed.

In the particular example shown, the latch bolt 25 may be retracted by acylinder lock 32 passing through an opening in the outer wall of themetal tube and secured in the mortise lock in the usual manner.

It will be seen that by the construction described, .the mortise lockmay be very readily mounted. It is first fitted into place in the metaltube with its face plate lying in the slot of the tube substantiallyflush with the tube surface at the edge of the door, and the partscarrying the spacing sleeves are then applied, and the fastening screws16, 16 screwed into place. The escutcheons 23, 24 are also secured tothe metal tube (but not to the lock) by the screws 29, 28. It is obviousthat although the screw 28 can be removed from the outside of the lock,the lock cannot be attacked in this way, because the outside escutcheon24 will still be held in place at two points, z'. e., where itscentering sleeve 24n (Fig. 8) fits an opening in the tube wall, andwhere its sleeve 30 engages a similar opening. The heads of the screw16, 16b are of course located at the inside of the door and are notaccessible from the outside.
